버어리種 담배의 鹽素營養에 關한 硏究 = A Study on the Chlorine Nutrition of Burley Tobacco Plants(Nicotiana tabacum L.)

다국어 초록 (Multilingual Abstract)

This study was carried out to survey the chlorine content of the soil and cured leaf in Burley tobacco growing area, to find out the effects of the different levels of chlorine fertilizer on yield, quality chemical constituents and physical properties of cured leaf, and finally to evaluate the effects of calcium, phosphorus, irons manganese and boron on the chlorine absorption by tobacco plants and on the chemical constituents of cured leaf.
The results obtained are as follows.
1.The chlorine concentration in soil at transplanting time in Kwang-ju growing area was higher than in Jeon-ju(1983), and paddy field soil showed higher concentration of chlorine than upland field did in Jeon-ju(1984). The chlorine concentration in soil was different between years, locations, and cultivated land (paddy field and upland field), but the concentration, on the whole, was under the levels that might effect the leaf quality.
2.The chlorine concentration in soil was highest around 40 days after transplanting, and after harvesting, the concentration decreased to half of transplanting time.
3.The distribution of chlorine through the parts of tobacco plant showed remarkable difference between years, locations, cultivated land and growing stages.
4.There was significant positive correlation between chlorine concentration in top soil and chlorine content of cured leaf.
5.Chlorine content of cured leaf in Kwang-ju area(1.79 %) was higher than that of Jeon-ju area(0.79 %), relatively.
6.When chlorine being applicated 4kg/10a or more, the cured leaf showed higher chlorine content and lower leaf quality remarkably. It was estimated that the critical application of chlorine was 3kg/10a.
7.There were positive correlation between chlorine and total alkaloid, and negative correlation between chlorine and potassium content of cured leaf.
8.As the chlorine content of cured leaf being increased, moisture holding capacity, the reflectant color of brightness, redness and yellowness in cured leaf had decreasing tendency.
9.Calcium application inhibited the absorption of chlorine and manganese, and increased the yield and quality of cured leaf.
10.The chlorine content of cured leaf grown in paddy field was high in iron and manganese application groups and highest in combined application of iron and manganese.
